GEORGE GREGG, OF LOWES MILL, VIRGINIA.

SAWINGr-MACI-IINE.

Specification of Letters Patent No. 16,435, dated January 20, 1857.

To all whom it may concern:

Be it known that I, GEORGE GREGG, of Lowes Mill, county of Monongalia,and State of Virginia, have invented a new and useful Machine or Sawmillfor Sawing Timber of Any Kind, called the Spring-Balance Double-ActingMuley Sawmill; and I do declare that the following is a full, clear, andeXact description of the construction and operation of t-he same,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

The nature of my invention consists in having two saws attached to theends of beams which are pivoted on a central fender post so that theybalance each other and require no more gearing than a single saw milland very little if any more power to drive them.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction.

I only use one fender post a a cut out in the center of the top to admitthe upper beam b b on each side of the beam and in the top of the fenderpost I form material grooves which admit two screw bolts c c. Thesebolts pass up through a gumelastic or any kind of spring d d. The use ofthe bolts is to draw the saws up to any degree of tightness desired. Thedesign of the spring on the top of the fender post and on which theupper beam rests is to relieve the strain which must otherwise come onthe machinery in its vibrations. The lower beam b rests on a centralstatic-nary pivot. The pitman e may be worked perpendicularly by beingattached to one end of the lower beam or horizontal if attached to theperpendicular lever f which is fastened to the center of said lowerbeam.

The saws g g are attached to stirrups 7L. These stirrups are fastened torods or straps of metal. These rods or straps are connected with theends of the beams c'. All

these connections work on joints or pivots.
